Generation and analysis of correlated pairs of photons on board a nanosatellite
Zhongkan Tang, Rakhitha Chandrasekara, Yue Chuan Tan +5
Satellites carrying sources of entangled photons could establish a global quantum network, enabling private encryption keys between any two points on Earth. Despite numerous propos…
The photon pair source that survived a rocket explosion
Zhongkan Tang, Rakhitha Chandrasekara, Yue Chuan Tan +3
We report on the performance of a compact photon pair source that was recovered intact from a failed space launch. The source had been embedded in a nanosatellite and was designed…
Correcting for accidental correlations in saturated avalanche photodiodes
James A. Grieve, Rakhitha Chandrasekara, Zhongkan Tang +2
In this paper we present a general method for estimating rates of accidental coincidence between a pair of single photon detectors operated within their saturation regimes. By fold…
Deploying quantum light sources on nanosatellites II: lessons and perspectives on CubeSat spacecraft
Robert Bedington, Edward Truong-Cao, Tan Yue Chuan +6
To enable space-based quantum key distribution proposals the Centre for Quantum Technologies is developing a source of entangled photons ruggedized to survive deployment in space a…
Space qualified nanosatellite electronics platform for photon pair experiments
Cliff Cheng, Rakhitha Chandrasekara, Yue Chuan Tan +1
We report the design and implementation of a complete electronics platform for conducting a quantum optics experiment that will be operated on board a 1U CubeSat (a 10 x 10 x 10 cm…
Radiation tolerance of opto-electronic components proposed for space-based quantum key distribution
Tan Yue Chuan, Rakhitha Chandrasekara, Cliff Cheng +1
Plasma in low earth orbit can damage electronic components and potentially jeopardise the scientific missions in space. Predicting the accumulated damage and understanding the comp…
Near-space flight of a correlated photon system
Tang Zhongkan, Rakhitha Chandrasekara, Yau Yong Sean +3
We report the successful test flight of a device for generating and monitoring correlated photon pairs under near-space conditions up to 35.5km altitude. Data from ground based qua…
Silicon avalanche photodiode operation and lifetime analysis for small satellites
Yue Chuan Tan, Rakhitha Chandrasekara, Cliff Cheng +1
Silicon avalanche photodiodes (APDs) are sensitive to operating temperature fluctuations and are also susceptible to radiation flux expected in satellite-based quantum experiments.…
